Needs more rubber Are those 31's ? Or 33's ? They are 34x10.5's, I will probably put 39's or 40's but maybe only 37's We will see. The first part was to built the "beast" SO it could handle that big of meats!!! i.e. 1-Ton axles, but still need lower gears. Right now the springs are only 4" lift, but I made custom spring mounts SO its closer to 6" right now. ALSO there is NO body lift BUT I cut the bottom 6 inches off of the body is the reason IT lOoks so tall. I need to build tube nerf bars. I plan on installing little flater and longer and softer front and rear leaf springs probably first (the reason for the custom adjustable spring mounts), then I will see what Tire fits best.
